Abstract

Topological properties of vortex fields have witnessed an increasing attention due to a wide spread of possible applications at both microwave and optical frequencies. In particular, we have recently shown that composite vortices, i.e. superposition of vortex fields with different topological charges, can be exploited to manipulate the radiation pattern of a microwave patch antenna. In this contribution, we further explore the generation and manipulation of composite vortices in order to design a single patch antenna that exhibits a sector radiation pattern and emulates the radiation properties of a dipole placed at a quarter of wavelength from a reflector.
